             Summary: Replace all occurences of new Integer with Integer.valueOf
                 Key: HIVE-21228
                 URL: https://issues.apache.org/jira/browse/HIVE-21228
             Project: Hive
          Issue Type: Improvement
            Reporter: Ivan Suller


Creating Integer objects with new Integer(...) creates a new object, while 
Integer.valueOf(...) can be cached (and is actually cached in most if not all 
JVMs) thus reducing GC overhead.
